-Configuration through a hibernate.properties-File
-
- The most simple way to configure the plugin is, to put all the
- hibernate-configuration in a <<hibernate.properties>>-file on your
- classpath. Put the file in the <<<resources>>>-folder. Maven will put
- it in the <<<class>>>-folder of your webapp, where it will be picked up
- by this plugin as well as by Hibernate 4.
-
- Doing so, the only additionally configuration needed, to activat the plugin
- is the following entry in the <<<plugins>>>-section of your <<<pom.xml>>>:
-
----------------
-<plugin>
- <groupId>de.juplo</groupId>
- <artifactId>hibernate4-maven-plugin</artifactId>
- <version>${project.version}</version>
- <executions>
- <execution>
- <goals>
- <goal>export</goal>
- </goals>
- </execution>
- </executions>
-</plugin>
----------------
-
- But be aware, that in this case the database-url, that is
- build in the application is the same that is used while testing, where
- the database is droped and recreated by the plugin.
- <<<So, you should never fire up this configuration on your production
- system, or your database might be erased!>>>
-
- Hence, you should specify a different url for testing like in the
- following snippet:
-
----------------
-<plugin>
- <groupId>de.juplo</groupId>
- <artifactId>hibernate4-maven-plugin</artifactId>
- <version>${project.version}</version>
- <executions>
- <execution>
- <goals>
- <goal>export</goal>
- </goals>
- </execution>
- </executions>
- <configuration>
- <url><![CDATA[jdbc:mysql://localhost/test-db]]></url>
- </configuration>
-</plugin>
----------------
-
- Configuration properties, that are set in the <<<configuration>>>-section
- of the plugin-configuration cannnot be overwritten elsewere (for details
- see {{Configuration-Method-Precedence}}).
- You never can overwrite them by accident when specifying a property on
- the commandline or in your <<<settings.xml>>>.
-
-Configuration through maven-properties
-
- Alternatively, it is possible, to configure the plugin via maven-properties.
- Each relevant configuration-option has a corresponding maven-property
- (for a full list see the {{{./export-mojo.html} Documentation of the export-Mojo}}).
- These are named after the
- {{{http://docs.jboss.org/hibernate/orm/4.1/manual/en-US/html_single/#configuration-hibernatejdbc} Hibernate JDBC Properties}}:
-
- * <<<hibernate.connection.driver_class>>>
-
- * <<<hibernate.dialect>>>
-
- * <<<hibernate.connection.url>>>
-
- * <<<hibernate.connection.username>>>
-
- * <<<hibernate.connection.password>>>
-
- So, instead of writing the hibernate-configuration in the properties-file,
- like above, you could put it in the <<<properties>>>-section of your
- <<<pom.xml>>>.
-
- Thogether with the plugin-definition from above, the following would
- be a complete configuration (again, the database-url was overwritten in
- the plugin-configuration, to be sure to have a separate database for
- testing):
-
----------------
-<properties>
- <hibernate.connection.driver_class>org.hsqldb.jdbcDriver</hibernate.connection.driver_class>
- <hibernate.dialect>org.hibernate.dialect.HSQLDialect</hibernate.dialect>
- <hibernate.connection.url><![CDATA[jdbc:hsqldb:res:org.my.path.production_db]]></hibernate.connection.url>
- <hibernate.connection.username>sa</hibernate.connection.username>
- <hibernate.connection.password></hibernate.connection.password>
-</properties>
-
-...
-
-<plugins>
-
- ...
-
- <plugin>
- <groupId>de.juplo</groupId>
- <artifactId>hibernate4-maven-plugin</artifactId>
- <version>${project.version}</version>
- <executions>
- <execution>
- <goals>
- <goal>export</goal>
- </goals>
- </execution>
- </executions>
- <configuration>
- <url><![CDATA[jdbc:hsqldb:target/db/testdb;shutdown=true]]></url>
- </configuration>
- </plugin>
-
-<plugins>
----------------
-
-Configuration through the plugin-configuration
-
- A third way for configuring the plugin is the plugin-configuration.
- The relevant configuration-parameters are:
-
- * <<<driverClassName>>>
-
- * <<<hibernateDialect>>>
-
- * <<<url>>>
-
- * <<<username>>>
-
- * <<<password>>>
-
- The equivalent of the configuration from the last section would look
- like this:
-
----------------
-<plugin>
- <groupId>de.juplo</groupId>
- <artifactId>hibernate4-maven-plugin</artifactId>
- <version>${project.version}</version>
- <executions>
- <execution>
- <goals>
- <goal>export</goal>
- </goals>
- </execution>
- </executions>
- <configuration>
- <driverClassName>org.hsqldb.jdbcDriver</driverClassName>
- <hibernateDialect>org.hibernate.dialect.HSQLDialect</hibernateDialect>
- <url><![CDATA[jdbc:hsqldb:target/db/fotos;shutdown=true]]></url>
- <username>sa</username>
- <password></password>
- </configuration>
-</plugin>
----------------
-
- The parameter <<hibernateProperties>> (name of the hibernate-properties-file
- to use, defaults to <<hibernate.properties>>) can only be configured through
- this approach.
-
- For more explanations, see the
- {{{./export-mojo.html} Documentation of the export-Mojo}}.
-
-{Configuration-Method-Precedence}
-
- The configuration is gathered in a fix order:
-
- [[1]] <<<hibernate.properties>>>
-
- [[2]] maven-properties
-
- [[3]] plugin-configuration
-
- If you are in doubt about where a configuration-value comes from, run
- maven with the {{{./debugging.html}debug-output}} enabled: <<<mvn -X hibernate4:export>>>
- and be aware, that maven-properties can be overwitten on the command-line,
- in your <<<~/.m2/settings.xml>>> and in a profile.
-
- The plugin-configuration comes last and overwrites everything else.
- That way, you can be sure, that a configuration-value, that is
- specified in the plugin-configuration will never be overwritten by any
- other configuration-method.
-
-
- If you realy need to overwrite plugin-configuration-values with
- maven-properties, you can use maven-properties in the plugin-configuration:
-
-----------------
-<plugin>
- <groupId>de.juplo</groupId>
- <artifactId>hibernate4-maven-plugin</artifactId>
- <version>${project.version}</version>
- <executions>
- <execution>
- <goals>
- <goal>export</goal>
- </goals>
- </execution>
- </executions>
- <configuration>
- <password>${my-password-property}</password>
- </configuration>
-</plugin>
